There is a set of data: 42, 44, 44, 46, 48, 48, 48, 50, 51, 51, 56______ The mode is______ .

There is a set of data: 42, 44, 44, 46, 48, 48, 48, 50, 51, 51, 56______ The mode is______ .

(1) The order from small to large is: 42, 44, 44, 46, 48, 48, 48, 50, 51, 51, 56, so the median of this group of data is 48. (2) because the most frequent number in this group of data is 48, so 48 is the mode of this group of data. So the answer is: 48, 48
